The following JEP with scope "SE" has been proposed to target JDK 22:

  464: Scoped Values (Second Preview)
       https://openjdk.org/jeps/464

  Summary: Introduce scoped values, which enable the safe and efficient
  sharing of immutable data within and across threads.  They are
  preferred to thread-local variables, especially when using large
  numbers of virtual threads.  This is a preview API.

The announced deadline for feedback to jdk-dev is Thu 7 Dec 15:00 UTC:

    https://mail.openjdk.org/pipermail/jdk-dev/2023-November/008480.html

If there are no unresolved objections at that time, then the JEP will be moved
to the Targeted state, indicating that the feature is expected to appear in
the specified release of the JDK Project.  For more information about states,
see the JEP Process document:

    https://openjdk.org/jeps/1

A dashboard that lists JEPs with "SE" scope may be found via a link on this
